Weighted Average Calculator with Plain Average Comparison
x402
Weighted Average Calculator with Plain Average Comparison is a paid API for AI agents from twin.unykorn.org, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-01).
Computes a weighted average of a list of values given corresponding weights, and returns the plain (unweighted) average alongside for comparison.

How this service works
Weighted average, with the plain average for comparison — Genesis402 / UnyKorn Operator Network
Output
Returns a JSON object with a boolean ok status, the result type labeled 'weighted-average', the computed weighted average and plain average for comparison, a generated_at ISO8601 timestamp, and a payment receipt containing tx_hash, amount_usd, and receipt_id.
Example use cases
GPA calculation from graded courses
“I have three courses with grades 85, 92, and 74, and credit hours of 3, 4, and 2 respectively — can you compute the weighted average GPA and also tell me what the plain average would be?”
Portfolio weighted return analysis
“My portfolio has three assets with returns of 5%, 8%, and -2%, and I have 50%, 30%, and 20% allocated to each — what's the weighted average return, and how does it compare to just averaging the returns equally?”
Survey response weighting by group size
“I ran a survey across three groups that rated satisfaction as 7, 8, and 6 out of 10, with group sizes of 200, 150, and 50 people — what's the weighted average satisfaction score versus the plain average?”
Technical details
Endpoint
POSThttps://twin.unykorn.org/weighted-average?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to compute a weighted average and want the plain average surfaced automatically for side-by-side comparison. Particularly useful for finance (portfolio returns), education (GPA), or survey analysis scenarios where different items have different levels of importance or representation. Choose this over a manual calculation when operating in an agentic workflow that already uses x402 micropayments.
Side effects
- Mismatched lengths between values and weights arrays causing a 400 error
- Missing or empty values/weights parameters returning a validation error
- Non-numeric values in the arrays causing computation failure
- Payment failure via x402 protocol preventing endpoint access
- Weights summing to zero causing a division-by-zero error
